Abstract (en)
[origin: EP0470021A1] The invention relates to a method for production of castings of aluminium or its alloys comprising integrated runners intended for the distribution of a lubricant or for the circulation of a heat-exchange fluid. <??>The method is characterised in that: - one or more previously shaped tubes of aluminium or aluminium alloys are placed in a mould, the ends of the tube or tubes being outside the mould or the cores inserted therein; - the alloy is poured into the cavity of the mould; - after removal from the mould, the excess parts of the tube or tubes are removed. <??>This method applies to the mass-production of castings having a system of internal runners, such as cylinder heads, compressor cylinders, lubrication systems, convectors, etc. <IMAGE>
